Application filed July 11, 1908. Serial No. 443,140.

To all whom it may concern:

Be it known that we, lViLLIAM HENRY HorLn, cotton-spinner, and TnoimsBARKER, consulting engineer, subjects of the King of Great Britain andIreland, residing, respectively, at 86 Chorley New Road, Bolton, in thecounty of Lancaster, England, and Church road, Smithills, Bolton,aforesaid, haveinvented new and useful improvements in elongating ordrafting and such like machines for the production of recondensed yarnor yarn of comparatively fine counts having the characteristics ofcondenser yarn, of which the following is a specification.

Our said invention relates to elongating or drafting and in some casescombined elongating or drafting and spinning machines of a more or lessnew class invented by us for the production of re-condensed yarn andwhich machines or parts thereof form the subject matter of United StatesPatents Nos. 7 08046 and 739877.

, This present invention particularly concerns the arrangement of andthe driving of the rotating or the moving parts of such machines.

lVe seek to so drive the machine that we shall be able to quickly removethe fancy the cylinder, and the dofi'er, when required, without anyconsiderable dismantling, and to readily replace the same. Heretoforethe removal (for grinding or other reason) and replacing of such wireclothed parts has been a difficultmatter and one which has consumed muchtime. Further than this, we seek to have, as far as convenientlypossible, a positive drive in respect to each moving part, for whereaswe used gear wheels for communicating motion to certain parts, certainother importantparts of the machine have heretofore been driven bystraps or hands and such bands involved the use of *arrier-pulleys andtightening devices which called for constant attention. F or example themain cylinder has been driven by a strap or band also the fanc as wellas the dofiing-comb and the rubbers. e find with continued experiencethat more certain control as to uniformity in the speed of revolution ormovement of such parts is desirable, and particularly with relation tothe cylinder drive, the fancy drive, the driving of the dofiing comb,and of the rubbers to reciprocate same.

If the band slips in driving the cylinder (in cases where the yarn isspun straight a 'ay) the twist is increased. Then with regard to thefancy it is necessary thatthe same should have a surface gain and onewhich can be uniformly preserved if it be desired to prevent a certainiineveimess in the yarn. The doffer comb too should always start withcertainty or ends may be broken down, while with any slip occurring inthe rubbers the yarn may not besufiiciently or uniformly rubbed, whichcauses some difiiculty in umvinding from the bobbins in case thematerial is spun or dealt with 011 an independent machine.

\Ve aim at obtaining a drive which will both allow of rapid and easyremoval of the required parts and provide for the positive actuation themoving elements (or certain of them) with intent of obtaining andpreserving a constant speed of movement, thereby giving greateruniformity, dispensing with certain parts, and overcoming difficulties.The way in which such parts are mounted and positively d'riven may varyconsiderably while still being within the scope of our invention, havingmentioned which, we now proceed to describe the best systems at presentknown to us and; by which the object of our invention can beaccomplished and the machine improved.

The attached drawings illustrate the ma chine and the improvements madein connection therewith according to our present invention.

In the said drawings: Figure 1 shows a side elevation of the newelongating frame or machine in its remodeled form, the main cylinder,the fancy, and the doffer being clearly indicated. Fig.2isa transversesection of the machine or frame and shows a considerable portion of thedriving gear. Fig. 3 is a plan view of the complete frame or machine fora limited number of ends, provision for a small number only being ilustrated in the drawn plan, owing to the limited space in the sheet,the figure requiring considerable space longitudinally. Fig.

3 is a detail view showing how the main cylinders are driven from themain or first motion shaft, the figure being drawn to a reduced scale. Fig. f shows a modification in the way of driving the cylinder shaft, therubber reciprocating mechanism. and the feed rollers, which modificationwill be fully dealt with later on in the specification. Fig. .3 is adetail diagrammatic view showing the gear connection between the shaft 6of the main cylinder and the shaft 50 of the feed roller, the relativesizes of the gears being changed from those shown in Fig. 2 for the sakeof clearness. Fig. 6 is an end view showing the cylinder and fancyshafts with their gear wheels.

In the construction of elongating frame or machine now being describedto the reader, and for the purposes of the new drive in accordance withour invention, we use a main shaft 1 which is suitably journaled and hasfast and loose pulleys 2, 3, the same being actuated from a line shaftor otherwise; This main shaft 1 carries two spur wheels (where two maincylinders in line with each other are used as the drawing shows) andthese two spur wheelsare lettered l, 4. Immediately above such shaft 1and spur wheels 4, 4: the main cylinders 5, 5 are located, the samebeing mounted on shafts 6, 6 and driven by spur wheels 7 7 which gearwith the spur wheels 41, l on the main shaft 1. The diagram Fig. 3 makesthis sufficiently clear. Each cylinder shaft 6 fits in bearings whichhave an adjustable or other base block 8 and a cover or pedestal cap 9,as very clearly shown in Fig. 1, whereby, on the removal of the caps 9 9the particular cylinder 5 can be lifted away without any seriousdiflicult-y being encountered and without any considerable dismantling.Fa cility in removing the fancy 10 and the doffer 11 are, as explained,points in our invention, and in the drawings the covers or caps 9, 9 areformed with fixed bends 12 which support angularly adjustable brackets13 in which arms 11 are guided and in which arms each fancy shaft isjournaled at 15. The screwed pinching studs 16. 16, serve to regulateangular adjustment of the bracket 13 by bearing on the projection 16 onthe fixed bend 12 and the screw 17 serves to set up the arm 14, the samepassing through the web of the bracket 13 and being held by lock nuts17*. A headed bolt with nuts, such bolt being lettered 18 serves toclamp the arm 14 and the bracket 13 to the bend 12 after ad justment hasbeen made. The arm let has a long slot 14: to allow of adjustment of thearm 14.

7 6 and 77 denote bushes for the fancy shaft and the main cylinder shaftrespectively. The bush 76 fits the bearing 15 and the bush 77 fits thepedestal 8 and both are gripped fast and form the bearing proper. Thefancy rollers 10 may be lifted away with the caps and fixed bendcomplete, or the caps of the journals for the fancy rollers may beremoved and the fancy lifted away alone. The system of carrying thefancy rollers 10 allows for ready setting up or adjustment of theclothed surfaces and also of radial movement of each fancy with respectto the cylinder. The doft'er 11 can also be removed after the fancy bytaking off the pedestal caps 19. I Adjusting spindles 19 passing throughthe bearing blocks 8 serve to adjust the dofl'er bearing blockshorizontally. The usual holding bolts serve to secure the v2 riousbearing blocks to the framing. Under our invention no gear wheels existor framing above these revolving parts to interfere with the liftingaway of the before described cylinders and rollers from their bearings.

e have so far described how the main cylinders are driven and the way inwhich the main cylinders, the fancy rollers, and the doffers can beremoved. Vi e now return to the gearing. The left-hand cylinder shaft 6carries a small spur wheel 20 which gears into the wheel 21 of acompound spur wheel running on a stud carrier 22 the other spur wheel 23gearing with a spur wheel 2% of a compound spur wheel on a stud carrier25 or elsewhere the other spur wheel 26 of this second compound spurgearing into a spur wheel 27 fixed on the (letter shaft this other spurwheel 26 also driving a spur wheel 28 fixed on a cross shaft 29. Thespur wheel 28' on the cross shaft 29 drives a spur wheel 30 on the lowerrubber shaft 31 which spur wheel 80 gears with a spur wheel 32 on theupper rubber shaft 33. This combination leaves room for easy access tothe upper rubber supports as the plan view Fig. 3 shows.

To drive the batching means or devices which take up the delivered endswe use a chain 31 which extends from a chain wheel 35 on the cross shaft29 to a chain wheel 36 on the shaft 37 a pinion 38 on such shaft drivingpinions 39 to rotate the drums (Z or the like upon which the batchingdrums or bobbins 6 rest. The gears 26, 27, 28, 30 and 32 are repeated onthe right-hand side and the motion therefor is derived from thecross-shaft 29.

For the purpose of actuating the feed rollers we take motion by spurwheels from the right hand pinion 20 which gears into the spur wheel 10of a compound spur wheel on the stud 11 the other spur wheel whereof d2gears with a spur wheel 43 on the axis 14 of which is a small spur wheel15 which drives the spur wheel 46 on the axis 47 whereon is also thespur wheel 48 which drives the spur wheel 4L9 and thereby the feedroller shaft 50 is driven. The feed lap drum or drums are driven byconvenient gearing, for instance, the feed roller shaft 50 may have agear wheel 51 gearing into the spur wheel 52 which drives the spur wheelon the axle 5 of the feedlap drum 54. This way of driving the feed lapdrum or drums may vary.

\Vith the object of driving the fancy 10 and also the dotting comb 63, aspur wheel 55 which is mounted on the cylinder shaft 6 is or may beused, the spur wheel 55 driving another. spur wheel 56 meshing therewithand attached on the shaft of each fancy whereby each fancy is drivendirect from a spur wheel 'on the main cylinder shaft. The spin wheels 55on each main cylinder shaft each gear into a carrier spur wheel 57 on astud or shaft '58 suitably supported in bearings and upon eachof saidshafts is a second spur wheel 59 which drives a spur wheel 60 fixed onthe comb motion shaft 61 which gives movement to the parts whichoscillate the comb shaft (31 and comb 68. It is obvious that this groupof gearing would exist at each end there being two comb shafts to drive,as the plan View Fig. 3 indicates.

The fancy shaft 10 is at a somewhat higher level than the cylinder shaftand such shaft is well and firmly supported in bearings as indicated andcan be readily and quickly removed as already explained.

The way of driving the doffer rollers indicated is advantageous becauseas they or their spur wheels under this present arrangement no longerdrive any moving part (see Fig. 2) the dofl'er is not deflected bystrain as was liable to occur before, and consequently closer and moreaccurate setting can be effected.

To drive the reciprocating mechanism for the rubbers we may use ahorizontal shaft 6 1 mounted in bearings and driven by bevel gear 65from the main shaft 1 such horizontal shaft 6% being provided with aspur pinion 66 which gears with'a spur wheel 67 in connection with orforming part of the rubbing device R. The means for reciprocating therubbers is illustrated in the before mentioned Patent 7 39,87 7

By our invention we at once simplify the driving, make same positive anddeterminable, and we dispense with all guide pulleys and tighteningarrangements, and get a better and more uniform product. In addition tothis, the indicated arrangement is such that we can with the greatestease remove or replace the cylinders, fancy rollers and doifers, whichis a point of the utmost importance, this being a job not easy ofaccomplishment under our earlier construction. Any required or desirablevariation in the gearing, or its disposition, we may make having regardto the object of our invention as set forth.

Fig. 4 is a plan view and shows a modified arrangement of driving so faras the disposition of the fast and loose pulleys are concerned and themanner of driving the main cylinder shaft. Also the way of actuating themeans which reciprocate the rubbers and of driving the feed rollers isslightly different. In this modification the fast and loose pulleys 2, 3are at the back of the machine and the cylinder shaft is driven by bevelgears 68 from the main short shaft 1. This short shaft 1 drives themeans which reciprocate the rubber by spur wheels 66* and 67*. The spurwheel on the lefthand side 20*, is the equivalent of 20 mentioned beforeand drives through 21, &c., up to 32. In this case the chain wheel 35 isrotated by 28 and communicates motion by chain at to operate the take-upor batching means. Practically the same train of gear exists on theright-hand side and can be followed by the lettered parts which receiveinitial motion from the long spur wheel 20* on the cylinder shaft 6. Todrive the feed roller shaft 50 the before mentioned spur wheel 20* onthe cylinder. shaft 6 actuates a spur wheel (39 compounded with a spurwheel 7 O which drives a spur wheel 71 compounded with 72. The wheel 72gears into 7 3 which is below and is compounded with 74 which in turndrives a spur wheel 75 fixed on the feed roller shaft 50 and thus therotation of the feed roller shaft is brought about. The axle 54* getsmotion from 50 through gear wheels 51, 52 and 53 as before related. Inthe machine illustrated in the drawings, the product is removed 011 thebobbins, and the ends are intended to be fed into a spinning machine forspinning and twisting as will be understood.

WVe declare that what we claim is.
